Amazon Cloud Service Level Agreement: A Comprehensive Overview
Amazon is known for its wide range of services, from online shopping to cloud computing. Amazon Web Services (AWS) is the cloud computing platform offered by Amazon. AWS provides a range of computing services, including storage, computing power, and database management. AWS is widely used by businesses of all sizes for its reliability, security, and scalability. However, like any other cloud computing service, AWS also has a Service Level Agreement (SLA) that outlines the terms and conditions of the service.
What is an SLA?
An SLA is a contractual agreement between a service provider and its customers that outlines the level of service that the provider will deliver. In the case of AWS, the SLA guarantees a certain level of uptime, performance, and availability of the AWS services. If AWS fails to meet these guarantees, customers are entitled to receive service credits.
AWS SLA Overview
AWS SLA covers most of the core services that AWS provides, including EC2, S3, RDS, and CloudFront. The SLA guarantees a monthly uptime percentage of 99.99% for each service. This means that for any given month, AWS will ensure that the service will be available for at least 99.99% of the time. If AWS fails to deliver the agreed upon uptime, customers are entitled to receive service credits.
How are Service Credits Calculated?
Service credits are calculated based on the percentage of uptime missed in a given month. The calculation of service credits depends on the service used and the pricing model. For example, in EC2, service credits are calculated as 10% of the monthly bill for the service that failed to meet the SLA. The maximum credit that can be provided is 100% of the monthly bill.
What is not covered under AWS SLA?
The SLA does not cover customer actions or any third-party applications or services. It also does not cover any service that AWS does not guarantee uptime for. These services are usually marked as “preview,” “beta,” or “experimental.” The SLA also does not cover any issues caused by external factors like natural disasters or power outages.
In summary, AWS SLA is a contractual agreement that outlines the level of service that AWS will provide. The SLA guarantees a monthly uptime of 99.99% for most of the core services provided by AWS. If AWS fails to deliver the agreed upon uptime, customers are entitled to receive service credits. It is important to note that the SLA does not cover customer actions, third-party applications or services, or external factors. Overall, the AWS SLA provides customers with peace of mind and ensures that AWS maintains a high level of service delivery.
